MetabolomicsSAR11 Cells Rely on Enzyme Multifunctionality to Transport and Metabolize a Range of Polyamine Compounds
In the ocean surface layer and cell culture, the polyamine transport protein PotD of SAR11 bacteria is often one of the most abundant proteins detected. Polyamines are organic cations at seawater pH produced by all living organisms and are thought to be an important component of dissolved organic ma...

MetabolomicsSearching for Drug Synergy Against Cancer Through Polyamine Metabolism Impairment: Insight Into the Metabolic Effect of Indomethacin on Lung Cancer Cells
Non-small cell lung cancer (NSCLC) is the most lethal and prevalent type of lung cancer. In almost all types of cancer, the levels of polyamines (putrescine, spermidine, and spermine) are increased, playing a pivotal role in tumor proliferation. Indomethacin, a non-steroidal anti-inflammatory drug, ...

MetabolomicsAftpo3 and Afdur3, the Aspergillus fumigatus Plasma Membrane Transporters of Polyamines, Regulate Polyamine Homeostasis and Itraconazole Susceptibility

Aspergillus fumigatus is a notorious opportunistic pathogen that causes Invasive Aspergillosis (IA) infections with high mortality in immunosuppressed individuals. Long-term antifungal drug azole abuse in clinical treatment and agriculture renders it ineffectual or drug resistant. Drug resistance...

MetabolomicsTargeted polyamine metabolomics of ATP13A4-deficient cellular and mouse models

ATP13A4 is a polyamine transporter enriched in astrocytes that regulates extracellular polyamine homeostasis. This study contains targeted LC-MS/MS metabolomics data from ATP13A4-deficient cellular and mouse models, including C8-D1A astrocytic cells, astrocyte-conditioned medium, mouse cortex, pl...

MetabolomicsLactiplantibacillus plantarum PS128 restores microbiota-driven polyamine homeostasis to alleviate autism-like behaviors in Fmr1 knockout mice

Background Autism spectrum disorder (ASD) is biologically heterogeneous and has limited mechanism-informed interventions targeting core behavioral symptoms. Emerging evidence suggests that gut microbial metabolism shapes neurobehavioral outcomes, yet the specific metabolic pathwa...

MetabolomicsSIN-3 transcriptional coregulator maintains mitochondrial homeostasis and polyamine flux
Mitochondrial function relies on the coordinated transcription of mitochondrial and nuclear genomes to assemble respiratory chain complexes. Across species, the SIN3 coregulator influences mitochondrial functions, but how its loss impacts mitochondrial homeostasis and metabolism in the context of a ...

MetabolomicsOA-HOXB9-ODC1-Polyamine Axis Mediates Metabolic Syndrome Promoting Endometrial Cancer Progression

Metabolic syndrome (MS) is a risk factor for both the development and progression of endometrial cancer (EC); however, the mechanism remains unclear. We found that polyamine metabolites are significantly elevated in the sera and tumor tissues of EC patients with MS (ECWMS). Hyperlipidemia is a cr...

TranscriptomicsTemporal transcriptional profiling of polyamine-depleted NIH3T3 cells
Polyamines are absolutely required for cell growth and proliferation. While polyamine depletion results in reversible cell cycle arrest, the actual mechanism of growth inhibition is still obscure. This work aimed at determining the cellular processes affected by reduction in the intracellular polyam...
